Because of meat (δια βρωμα). "Because of food."

In love (κατα αγαπην). "According to love" as the regulating principle of life. See Romans 14:1 where Paul pleads for love in place of knowledge on this point.

Destroy not (μη απολλυε). Present active imperative of απολλυω, the very argument made in 1. Corinthians 8:10.

With thy meat (τω βρωματ σου). Instrumental case, "with thy food." It is too great a price to pay for personal liberty as to food.
